Newly re-designed and manufactured, these beautifully machined aluminum hubs come with a generously thick rubber tire for maximum traction (ideal for minisumo, like our 1st place finishing Strong Bad!!).

The tire mounted on the hub measures in at 31.2mm (1.23in) diameter and overall width (including set-screw flange) of 11mm (0.67in) wide. The hub is drilled for a 3mm axle ideal for the GM12a-14a/18 series of gear motors! It's a nice, fat, beefy wheel ideal for small robots! Secure it to your motor shaft with the included 4-40 hex grub/setscrew (requires 0.050 hex wrench, like our HexW050).
